Gas-liquid separator, compressor assembly and air conditioner

Abstract

A gas-liquid separator relates to the technical field of air conditioning. The gas-liquid separator includes a housing, an outlet pipe and a suction pipe. The outlet pipe passes through the side wall of the housing to the outside of the housing. One end of the suction pipe extends to the bottom of the inner cavity of the gas-liquid separator. The other end of the suction pipe One end is connected to the outlet tube. The compressor assembly includes the aforementioned gas-liquid separator. The air conditioner includes the aforementioned compressor assembly. This is beneficial to shorten the length of the outlet pipe, thereby increasing the first-order resonance frequency of the refrigerant, preventing the suction frequency of the compressor from significantly exceeding the first-order resonance frequency of the refrigerant during high-frequency operation, and making it easier for the compressor to generate Suction boosting effect to enhance the air intake efficiency of the compressor and enhance the performance of the compressor; in addition, the setting of the suction pipe facilitates the lubricating oil at the bottom of the gas-liquid separator to be sucked into the compressor, so that the compressor is continuously lubricated, ensuring The compressor runs reliably for a long time.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a gas-liquid separator, a compressor assembly and an air conditioner. Background technique [0002] In the prior art, there are known compressors that utilize the effect of suction boosting. Since the compressor periodically sucks air from the gas-liquid separator, the refrigerant in the gas-liquid separator forms periodic pulsations, and When the pulsation frequency of the refrigerant reaches the suction resonance frequency, the pulsation amplitude of the refrigerant in the gas-liquid separator reaches the maximum, and the suction frequency of this type of compressor is equivalent to the suction resonance frequency (the suction frequency of the compressor is generally not greater than the suction resonance frequency), the pressure wave generated by refrigerant resonance produces a suction boost effect on the suction of the compressor, which in turn increases the amount ...

Problems solved by technology

[0006] However, since the outlet pipe generally passes through the bottom of the gas-liquid separator, shortening the length of the outlet pipe means simultaneously shortening the length of the gas-liquid separator and reducing the capacity of the gas-liquid separator, which means It is necessary to weaken the function of the gas-liquid separator, which increases the possibility of the compressor being subjected to liquid shock and affects the performance of the compressor.

[0007] In this regard, the patent with the publication number CN205349734U describes a technical scheme in which the outlet pipe passes through the side wall of the gas-liquid separator to the outside of the casing, so that only the length of the outlet pipe can be shortened without Shortening the length L of the outlet pipe of the gas-liquid separator will not affect the capacity of the gas-liquid separator. However, this will easily cause oil accumulation in the area below the outlet pipe of the gas-liquid separator, reducing the lubricating oil in the compressor. This affects the reliability of the long-term operation of the compressor; in addition, since the outlet pipe passes through the side wall of the gas-liquid separator to the outside of the casing, most of the outlet pipe extends into the inner cavity of the gas-liquid separator. This makes the outlet pipe prone to greater vibration when the compressor is running, which can easily lead to increased noise, and may even cause damage and breakage of the outlet pipe
